This module tests the Laplace distribution.

Test 1: test_pdf_cdf_ocatave()
         Compare pdf, cdf against results obtained from GNU Octave.

Test 2: test_cdf_quantile_symmetry()
         Checks if quantile is the inverse of cdf by testing
         quantile(cdf(x)) == x

Test 3: test_hazard_pdf_cdf_symmetry()
         Checks the relation between hazard, pdf and cdf.
         hazard = pdf/(1-cdf)


Test 4: test_location_scale_symmetry()
         Checks the pdf, cdf invariant for translation and scaling invariant
                 cdf(x,location,scale) = cdf( (x-location)/scale, 0, 1)
         scale * pdf(x,location,scale) = pdf( (x-location)/scale, 0, 1)

Test 5: test_mmm_moments()
         Tests...
         mean   == location
         mode   == location
         median == location

         standard_deviation = sqrt(2)*scale
         skewness == 0
         kurtosis == 6
         excess kurtosis == 3

Test 6: test_complemented()
         Test the cdf an quantile complemented function.
         cdf(L,x) + cdf(complement(l,x)) == 1
         quantile(L,p) == quantile(complement(l,1-p))

Test 7: test_bad_dist_parameters()
         Test invalid distribution construction.

Test 8: test_extreme_function_arguments()
         Test x = +/- inf. for cdf(), pdf()
         Test p ={0,1} for quantile()
